In this paper, a novel microwave oven power supply based on high frequency resonant convertor is studied. The structure of the convertor, the core control chip and the drive circuit are analysed in detail and the topology of the convertor is also simulated. Then the experiment results verify that this novel microwave oven power supply is with zero-volt age soft switching, low switching loss and high frequency. The efficiency of power supply is improved.
